A study on the morphology of the suprascapular notch and its distance from the glenoid cavity.

Introduction: A suprascapular nerve entrapment can occur at the suprascapular notch or at the spinoglenoid notch. So, the size and shape of the suprascapular notch are associated with suprascapular entrapment neuropathy as well as with an injury to the suprascapular nerve in arthroscopic procedures. The knowledge on the variations along the course of the nerve is important in understanding the source of the entrapment syndrome.
